I’ve been thinking a lot about Kratovil’s chances lately, since I have been represented by Andy Harris in the State Senate for the past 8 years and really cringe at the idea of him becoming a congressman and embarrassing the hell out of my home state, so I decided to do a little bit of analysis concerning Kratovil’s 2008 win to see if the conventional wisdom held true.
The conventional wisdom of the race is that Harris lost because, while running up big margins in his home in the Baltimore suburbs on the Western Shore, he could not overcome Kratovil’s margins on the Eastern Shore. Indeed, Kratovil did run a region-specific campaign against Harris, and did win all of the Eastern Shore counties while losing all of the Western Shore counties, but I’ve found that this obscures a few key facts.
First of all, Kratovil improved on Obama’s margins in EVERY part of the district; some more than others, yes, but overall Harris was such a bad candidate that he even underperformed McCain in the parts of Baltimore and Harford counties that he has represented for the past 8 years.
Second of all, the shifts on the shore were not all even. Kratovil overperformed Obama more in some counties than others. I decided to do a regression in Excel to see to what extent the variance of Kratovil’s numbers coincided with the variance in Obama’s numbers.
Here is a graph that plots the percentages with a regression line and equation:
Here is the data chart, with Kratovil’s percentage as predicted by the model from the regression line, and the difference between the predicted and actual results (highlighted in yellow are the counties where Kratovil overperformed his across-the-board shift):
As you can see from the r-squared value, the line fits the data about 75% of the time (which I’ve been told by professors is considered high for political research). Additionally, I found the correlation to be 85%, meaning that 85% of the time, the relative variance of Kratovil’s numbers can be explained by the relative variance of Obama’s numbers. This is very high, and although the same might be true of almost any politician (including people like Chet Edwards), the fact that it is so high shows that what we saw was more of an across-the-board rejection of Harris and less of a region-specific phenomenon (which would show less correlation due to a lot of overperformance in one area and underperformance in another). In fact, if you look closely at the toplines, you can see that many of the counties that Kratovil did win actually had less distance to go in voting Democratic than did the counties that he lost. Overall, the Western Shore counties are just a great deal more Republican than the Eastern Shore counties.
In most counties, Kratovil actually underperformed his across-the-board 10% shift, but the one region where he really overperformed his shift was in the upper Eastern Shore (Queen Anne’s County, Kent County, and Caroline County). This make sense, as Kratovil is from this region.
Additionally, he underperformed his across-the-board 10% shift somewhat on the Western Shore (as to be expected), but not nearly as much as one would expect. (I am including Cecil County as Western Shore just to clarify)
On the lower eastern shore, Kratovil performed at about his overall shift for the whole district. So to recap, Kratovil improved over Obama everywhere, improving the most in the Upper Shore, the least on the Western Shore, and at about his average improvement in the Lower Shore.
All of this underscores how delicate Kratovil’s position really is. If the number of voters willing to vote for Obama drops below 39%, then Kratovil is toast unless he overperforms by more than he did last time. He additionally cannot get too comfortable with the idea that he won based on an Eastern Shore-based coalition, since he actually picked up a lot of votes on the Western Shore as well.
To win, Kratovil needs to:
-Not allow Harris to gain any ground on the Western Shore over what he got last time. Basically, he needs to hold the same margins, since he is unlikely to go up any further here (although winning Anne Arundel is a possibility)
-Keep his unusually high margins on the Upper Shore that are unlikely to go up much more.
-Overperform his last election numbers on the Lower Eastern Shore for some insurance. I feel that he could do this if he gets voters in this area to really think of him as their own even more than they already have (more like the voters in the Upper Shore have).
As a bonus, I’ve included a map showing the percentage of voters who live in each part of the district.
Let me know what you think.
